Mishimoto Thermal Bypass Valve Kit for Jeep Grand Cherokee (2016-2021)

The transmission is a critical component in your Jeep Grand Cherokee, responsible for handling significant torque from its powerful V8 or 3.0L EcoDiesel engine. This immense power generates heat, and without proper dissipation, it can lead to transmission failure. While the stock transmission cooler works to manage fluid temperatures, its effectiveness is limited by the factory thermal bypass valve.

Protect Your Transmission

The stock 8-speed transmission's cooling system relies on an in-line thermal bypass valve to regulate fluid flow to the cooler. Its primary function is to prevent fluid from reaching the cooler until the transmission reaches optimal operating temperature. However, the thermostat within this valve is a known weak point and is prone to failure. When this occurs, the fluid never circulates to the cooler, leaving your transmission vulnerable to overheating, especially under demanding conditions like towing or spirited driving.

• Direct Fit Replacement: Designed as a direct replacement for the factory valve.
• Enhanced Cooling: Ensures constant fluid flow to the transmission cooler, even when cold, preventing overheating.
• Durable Construction: Built with high-quality materials for long-lasting performance.
• Prevents Overheating: Critical for maintaining transmission health during towing, off-roading, or high-performance driving.
• Vehicle Fitment: Specifically engineered for 2016-2021 Jeep Grand Cherokee models with 3.0L, 3.6L, 5.7L, and 6.4L engines.

Don't let a faulty thermal bypass valve compromise your Grand Cherokee's transmission. Ensure optimal cooling and extend the life of your drivetrain with this essential upgrade from Mishimoto, available at GGCRACING.
